MACHINE FOR SHAPING BOTTOViS OF SHOES.

SEECFICATION forming part of Letters Patent No. 666,343, dated January 22, 1901.

Application filed September 14, 1899. Serial No. 730,414. (No model.)

To all whom t may concern:

Beit known that I, ELOUILD DUPLEssIs, a subject of Her Majesty the Queen of Great Britain, residing at St. Hyacinthe, county of St. Hyacinthe, Province of Quebec, Canada,

have invented certain newr and useful Improvements in Machines for Shaping the Bottoms of Shoes; and I do hereby declare that the following is a full, clear, andexact descrip- Io tion of thein vention, such as Will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in sole leveling and shaping machines for the bottoms of slices; and the chief object in view is the production of a machine which will be entirely automatic in its operation after the work shall have been placed on the jack and the machine started.

zo A further object is to equip the machine with means whereby the entire sole or shoebottom may be uniformly shaped and the pressure regulated so as to supply the exact amount of pressure required by bottoms of varying thicknesses without further attention of the operator.

A further object is to equip the machine with an improved flexible'sole-shaping roll which shall be self-adjusting or automatic in accommodating and ada pting itself to the contour of the sole and the shank thereof, and with this self-adjusting flexible roller are combined a pressure mechanism and a man ually-operable controlling device. Said pressure mechanism acts on the individual members of the selfadjusting shaping-roll, so as to give the necessary press ure thereto, particularly when the members break, so as to assume divergent relation in conforming to the contour of the 4o sole andthe shank thereof, and, furthermore,

this pressure mechanism for the flexible shaping-roll has a shiftable element that may be easily adjusted by hand, so as to vary the pressure exerted by said mechanism on the members of the flexible shaping-roll, Whereby said shaping-roll may be adapted to exert the requisite pressure on soles of Varying thicknesses. The manually-operable shifting device for the exible shaping-roll pro- 5o vides an emergency controller which may be availed of to actuate said roll in a manner to assume divergent relation Without stopping the machine-that is to say, the roll may be controlled While it is pursuing its traversing path over the jack, whereby said roll may be adapted to peculiar-shaped slice-bottoms.

A further object of the invention is to provide means for automatically reversing the movement of the swinging carrier-frame on which the jack is mounted, said means in- 6o cluding` a reversible friction drive-gear and a variable stop-motion,which permits the swinging or arcuate motion of said frame to be varied according to the sizes of shoes which it may be desired to apply to the last.

Y A further object is to provide an improved means for supporting a jack in operative relation to said flexible shaping-roll and permitting said jack to move in a path approximately at right angles to the traversing move- 7o ment of the shaping-roll.

A further object is to provide an improved means for holding a toe-last in adjustable relation to a part of the swinging jack.

A further object is to provide an adjustable last-support which is adapted to be easily and quickly removed from the jack.

To these ends the invention consists in a machine for shaping the bottoms of shoes, constructedsubstantially as hereinafterillus- 8o trated and described, and defined in the appended claims.

Referring to the drawings, in which similar letters of reference indicate similar parts throughout the several views, Figure l is a view in perspective of a machine for shaping the bottoms of shoes, constructed in accordance with this invention. Fig. 2 is a view in elevation thereof. Fig. 3 is a similar view showing the other side of the ma- 9o chine. Fig. 4 is a view in elevation, partly in section, to show details of construction. Fig. 5 is a similar view, drawn on an enlarged scale, showing the lower portion of the machine. Fig. 6 is a top or plan View. Fig. 95 7 is an end elevation viewed from the rear of the machine. Fig. S is a similar view looking from the front of the machine. Fig.

Fig. ll is a view in perspective of the adjustable weight, showing the mechanism for adj ustiug the weight upon its supportingrod. Fig. 12 is a view in perspective of the flexible shaping-roller and a portion of its adjusting mechanism detached from the machine. Fig. 13 is an end view thereof, showing the flexible roller adjusted so as to shape the edges of the bottom. Fig. 14 is a detail View of a portion of the adjusting mechan- .ism of the iiexible shaping-roller.

In machines for shaping the bottoms of shoes as ordinarily constructed it is necessary for the operator to swing the j ack-frame by hand as the bottom is fed to the shapingroller in order to properly shape the edges of the bottom because of the use of a rigid shaping-roller. This operation not only necessitates tiresome labor, but is defective, in that as one edge of the bottom is pressed by the shaping-roller the other edge has a tendency to bulge up, rendering it necessary to pass the bottom repeatedly beneath the shapingroller and resulting in defective bottoms, it being almost impossible to shape both edges ot' the bottom uniformly. To obviate these defects` and lessen the labor attending the shaping of bottoms, the machine herein described has been devised, whereby the entire bottom is uniformly shaped and the pressure regulated so as to provide the exact amount of pressure required by bottoms of varying thickness without requiring the personal efforts or attention of the operator.

In the drawings, A represents a suitable frame, which may be of any usual or preferred form. Suitable bearings d are fixed upon said frame, in which is journaled the operating-shaft a, having a balance-wheel u? at one end and suitable pulleys d3 and a4 at the other end, one of which is loose, which are connected by a suitable belt to the source of power. (Not shown.) A belt-shifting device A, which may be of any usual or preferred form, is provided for applying and shutting off the power. At an intermediate point upon the shaft a' are fixed two disks a6, which are suitably spaced, between which is eccentrically iixed a crank-shaft ai, upon which is sleeved the crank-rod as, as best shown in Fig. 4. Upon the shaft a', adjacent to the balance-wheel ft2, is fixed a frictiondisk a, having at its outer face a gear-wheel um, which meshes with a gear-wheel a, fixed upon the outer face of the friction-disk am, which is fixed upon a shaft a, journaled in suitable bearings mounted upon the frame A.

A standard B is mounted upon the frame A adjacent to the shaft a and is provided with suitable bearings, in which is journaled a hollow shaft or sleeve l), having the eccentric cam b. Within the hollow shaft b is a shaft b2, arranged eccentrically with respect to said cam b', and fixed upon the outer end of said shaft b2 is the friction-wheel b3, which is adapted to be thrown into and out of engagement with the friction-disks a9 and 0.12, as best shown in Fig. 5.

Fixed to the hollow shaft l) is an upwardlyprojecting lug b4, which is provided upon its upper end with the lateral extensions b5 and 19', which project in opposite directions upon each side of the said lug b4. Pivotally connected with the extension b5 is au operatingrod bi, which is adjustably connected at its other end to an operating-lever B by means of a pin adapted to engage one of a series of perforations formed in said lever B.

From the above description it will` be apparent that by moving the lever B' the friction-wheel b3 maybe thrown into or out of engagemeut with the friction-disk a, or L12 or retained in an inoperative position between the two disks a9 and am and out of engagement with either. It is also obvious that the friction-wheel b3 can be rotated in either direction, in accordance with the friction-disk with which it is thrown into engagement.

Pivotally supported in suitable brackets mounted upon the frame A is the oscillating frame D, which is provided at one end with a toothed segment cl, which is adapted to mesh with a pinion d', fixed upon the shaft b2, as best shown in Fig. 4. The other end of the oscillating frame D is formed into a yoke having upwardly-extending arms cl2 and d3, within which is pivotally supported the jack-frame D, so as to permit said jack-frame to swingfreely in said oscillating frame. The upper end of the arm d2 is provided with two outwardly-extending pins d, upon which 'are rotatably mounted the friction rollers (l5. (Clearly shown in Fig. l.)

The jack-frame D (shown in detail in Fig. 9) is also yoke-shaped and conforms substantially in shape with the yoke of the oscillating frame D. One ot the arms d6 of thejackframe D is provided with a pivotpin (Z7, which is adapted to engage an eye formed in the upper end of the oscillatingr frame D, while the other arm Z8 is provided with a lateral extension d. in which is formed a series of openings or sockets d. Upon the under surface of the extension Z9 is secured a plate du, which is adapted 1o rest and slide upon the friction-rollers d5. (Olearlyshown iii-Fig. l.) A block E, having a threaded opening c, is adjustably mounted upon the upper face of the extension (Z9, the contacting surfaces of the block and extension being suitably curved in order to maintain the proper adjustment.

A toe-cap E' is secured to the block E by means of a threaded shank e engaging the opening c, so as to permit of the vertical adjustment of said cap. The upper surface of the toe-cap E is suitably curved orhollowed, so as to adapt it to receive and retain the toe portion of the last. The under surface of the toe-cap E is provided with a notch e-, which is adapted to receive the end of a springpressed pin e3, mounted in the block E, by means of which the toe-cap is prevented from IOO IIO

IIS

accidentally turning. A recess e4 is formed in the upper surface of the block E to receive the end of the pin e3 when the sameis pressed down to permit of the adjustment of the toecap. The extremity of the shank e is provided with a pin e5, which is adapted to engage one of the sockets d10, by means of which the block E is held in its adjusted position.

A hollow arm E2 is formed integral with the jack-frame D' and exten ds upwardly between the arms d6 and d8. The upper end of the arm F2 is provided with a threaded collar e6, and within said collar is loosely7 sleeved the adjusting-nut e7, 'which is of slightly smaller diameter than the opening of said collar e6 and is provided with a flange upon its upper end. A last-supporting rod es is threaded in the nut e7, so as to be adjusted vertically, and its lower end is engaged by a suitable spring e, the end of which is secured to the arm E2, by means of which the rod e8 is held back to the limit of its movement in one direction in the collar e6. By means of this construction the last, which is secured in the usual manner upon the end of the rod es, is adapted to move slightly under the pressure of the shaping-roller.

It is apparent from the construction above described that the rotation of the shaft h2 will cause an upward or downward movement to the oscillating frame D corresponding with the direction of rotation of the frictionwheel b3, and this movement will force or feed the last carrying the bottom being operated upon back and forth under the shapingroller.

To a lug formed upon the lower portion of the oscillating frame D is pivoted a rod H, the outer end of which plays freely in an opening formed in the lateral extension 1) of the lug` h1. At suitable points on the rod H are adjustably iixed the stops h and h', located, respet'ztively, on either side of the said extension h6, as shown in Fig. 5. During the movement of the oscillating frame D the rod H moves freely through the extension b until one or the other of' the stops h or 7L' comes into contact therewith, whereupon the hollow shaft l) will be rotated and the frictionwheel b3 thrown out of contact with its operating-disk and into contact with the other, whereby the movement of the oscillating frame is reversed. This construction also prevents the toothed segment d from running olf the pinion d. Bysuitablyadjusting said stops 7L and h upon the rod lil the oscillating movement of the frame D may be limited to suit the requirements ofthe work being done.

Upon the rear of the frame A is the standard F, in which is pivoted the link f, the lower end of which is pivotally connected with the crank-rod cts. The upper end of the linkfis pivotally connected with the rod j", which extends forwardly over the top of the oscillating frame D. Upon the rod f are fixed the brackets and within which are journaled the shafts fL and f5, in the forward extremities of which are journaled the two sections f6 and f7 of the flexible shapingroller F. The general conformation of this shaping-roller F' corresponds to those in common use, being of the smallest diameter at the center and curving from thence to the outer ends. The shifting roller forming an important feature of this invention is, however, made in two similar sections f6 and f7, each of which is rotatably supported in the ends of the shafts fl and f5, as clearly shown in Figs. l2 and i3. One of the sections is provided with a socket and the other with a pin at their meeting` faces, whereby they are supported under pressure and retained in proper position with respect to each other.

At a suitable point upon each of the shafts f4 and f5 is fixed a sleeve f8 and fg, having toothed segments flo and f upon their adjacent faces, whereby the movement of one shaft will cause a corresponding movement of the other shaft. One of these sleeves, preferably f5, is provided with an outwardly-extending lug fw, having upon its extremity a friction-roller fls. (Clearly shown in Figs. l2, 13, and 14.) This friction-roller flengages a guideway formed by a bracket fm, slidably mounted upon the upper end of a supporting-rod fl. Pivotallyconnected with the bracket fm is an operating-lever F2, the rear end of which is pivoted to a rod fw, adjustably secured in an arm f1?, fixed to the rod fh". (See Fig. l.) A suitable spring fls is coiled about the rod f15 and serves to return the lever to its normal position after having been depressed by the operator.

By reason of the connection of the crankrod as with the disk et it will be apparent that the rotation of said disk will impart a horizontally-reciprocating movement tothe shaping-roller F, while depressing the lever F2 will force the shaping-roller to assu methe desit-ed curvature to simultaneously shape both edges of the bottom.

To the bracket f3 are pivotally connected the rods G, which are pivot-ally connected at their lower ends to lugs g, fixed upon a crossbar g'. (See Figs. 4L, 7, and 8.) Upon the cross-bar g' is supported a strong spring` g2, which is secured at one end to a suitable tiebolt g3, while the other end of this spring is supported in a notch formed inthe curved projection g4 of the lever-bar g5, which is pivotally supported by means of a tie-bolt Q6 in the lower part of the frame A. (See Fig. 4t.) The lever-bar j extends beneath the frame A and along the eut-ire length thereof, and slidably secured upon said lever-bar is the weight Gr', which is provided with an indicator-arm g?. A suitable scale is formed upon the side of the frame A, whereby the amount of pressure upon said lever-bar, and consequently upon the shaping-roller Fl, cati be accttrately determined. vided with perforated lugs g8 and a suitable stop gg, and a handle-rod gl0 is slidably sleeved in the perforations of said lugs g8.

The weight G' is pro- IOO IOS.

IIO

One end of the rod gw is provided with a suitable handle, while the other end is bent at an angle, whereby it may be turned into and out of contact with the stop g, as is clearly shown in Fig. ll. By means of this construction the rod gw can be made of sufficient length to permit of the convenient adjustment of the weight to any point upon the lever-bar g5 without projecting an objectiona-ble distance beyond the frame A.

It is believed that the operation of the machine will be fully understood in view of the above description without further detailed explanation.

While I have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.
